SamF: I reckon you could get away with a bit less SNRM as well.
That's the plan, but I want to take it slow. I'm still amazed you got it up to 9ish(?) without a drop in DLM profile. ;-) I'm really hoping DLM isn't "broken" or something lol.
Anyway, after a few days on -60 it seemed to end up with CRCPM a little over 3.
So now I just bumped up DownstreamMarginOffset to -65 on the Fritzbox, so a couple more data points below. One interesting thing I note is that in "real" speedtests my upload speed seems to have been adversly affected by this latest tweak. While download on most speedtests at -60 was 40.3Mbps and has now bumped up 40.9, my upload which has been a very solid, consistent 9.4-9.5 for a long time, but has now dropped to ~9.1-9.2 with this latest tweak... not sure if it's actually related or not.
